LUBRICATING-PUMP.

SPECIFICATION forming part of Letters Patent No. 3Gv4,258,'dated June '7, 1887.

Application iled Juno 1,1886. 4

To all whom, t may concern:

Be it known that l, FRANK KEATING, of Milwaukee, in the county of Milwaukee and State of Visconsin, have invented new and useful Improvements in Lubricating-Pumps; and I do hereby declare the following to be 'a full, clear, and exact description of said invention, reference being had to the accompanying drawings, and to the letters or glires of reference marked thereon, which form a part of this specification.

My invention is of a lubricator for ,the use of liquid lubricant, and is an adjustable automatic pumping device which may be adjusted to supply a small or large amount of lubricant intermittently at long or short intervals, as

desired.

In, the accompanying drawings, Figure l is a front elevation ot' my lubricator, the pump being in section centrally vertically. Fig. 2 is a side elevation of the lubrieator.

rihe same letters refer to like parts in both the views.

A is the body or case of thelubricator, and

. contains a vertical chamber in which the piston or plunger H reeiproeates. .The case A is attached to and su pported on the base B, through which base a receiving-duct, D, and a discharging-duet, E, lead into the bottoni of the chamber in case A. The receiving-duet D is provided with a cheek-valve, F, adapted to open and permit the inflow of the lubricant, butto close and. stop its outllow. The discharging-duct E is also provided with a checkvalve, Gr, adapted to open and permit the out- Ilow of the lubricant, but to close and stop its return or inllow. Both of these valves F and G are plug-valves adapted to close by gravity; but other forms of check-valves would perform their functions.

The small valve-chambers in which the valves F and G are located and operate are covered by plug-nuts turning into the top of the base-plate B'. These valves may be readily examined or removed for repairs by simply unscrewing the plug-nuts over the chambers in which they are. 4

The piston or plunger H, which reci procates air and liquid tight in the chamber in the case A, is, for convenience in construction, Va straight cylindrical rod. Any other form of Serial No. 203,692. (No model.)

plunger or piston with a stem would perform the same function. The plunger H has packing I about it at the top of the case A, which is secured in place by the packing-nut J turning on the top of the case A.

A bracket, K, is at its bottom adjustably clasped upon the case A, and in its top has a journal-bearing inwhich a spindle is supported and rotates or oscillates, thespindle being at right angles to the plunger H. The bracket K being adjustable on case A, the spindle L may be caused to extend horizontally in any direction from the case. A wheel, M, is pierced eceentrically by and supported rigidly on the inner end ot' the spindle L.

The upper end of the stem otthe plunger H is expanded into a flat or plate-like part, N,

provided with a vertical slot, O, into which the inner end of the spindle L enters, permitting of a reciprocal movement of the plunger. This expanded part N of the stem of the plunger H is provided with two horizontal shoulders or flanges, l? P, as far apart as the diameter of the cam-wheel M, between which shoulders the wheel M fits and revolves or oseillates, and against which it bears, one shoulder being above and one below the wheel, whereby as the spindle L and cam-wheel M, rigid thereon, rotate or oscillate the plunger H is raised and lowered.

On the inner end of the spindle L is a sleeve, Q, having an expanded head provided with saw-teeth, which clutch with corresponding saw-teeth on the face of the hub It, which teeth are so constructed with straight engaging front edges and beveled rear edges that as the sleeve Q is rotated forwardly its teeth engage the teeth on the hub R and carry the spindle forward in rotation with the sleeve, and as the sleeve is rotated rearwardly the teeth of the sleeve slip past the teeth of the hub R. The sleeve Q is held up to engagement with the hub R by the coiled-wire spring S, inserted around the spindle between the outer end of the sleeve and a collar, T, fixed on the spindle. A lever-handle, U, is affixed rigidly to the sleeve Q which, being caused to oscillate vertically,either by being attached to machinery therefor or otherwise, will oscillate the sleeve alternately forward and back, and

thereby rotate the spindle, whereby the cam- IOO -wheel Mis caused slowly` to revolve and raise and lower the plunger H with long and full strokes. I alsoiprovide a set-screw, V, turning through a lug, W, integral with hub R, into a loosejawror clamp, W', adapted to bear against the head of the sleeve Q, whereby the Sleeve may be rigidly clutched or affixed to the hub R. This rigi'd connection between sleeve Q and hub R being made, the oscillation of the lever-handle U will correspondingly oscillate the cam-wheel M and raise and lower the plunger H. A greater or less reciprocal movement of the plunger H may be secured with the same oscillatory movement of the leverhandle U by so adjusting the cam-wheel M that its longer radiusshall be in line with or at right angles to the plunger 01 at some angle between these directions, as desired, and clamping the sleeve Q rigidly to the hub R.

It will be seen that the upward movement or" the plunger I-I will cause the lubricant to enter the chamber in case Afrom the reservoir or other .source of supply through the duet D, and that the downward stroke of the plunger will force thev lubricant out of the chamber through the duct E to and upon the parts to be lubricated.

Vhat I claim as new,and desire to secure by Letters Patent, is-a l. In an automatic lubricator, a receiving and a discharging duct leading,respeetively,to and from the plunger-chamber, in combination with two check-valves, one in thev receiving and one in the discharging duct, said valves being each locatedoutside of the lubricant chamber or tank in a small chamber therefor in its duct, which chambers are each closed by a removable cover, whereby said valves are l capable of being repaired or renewed without 'removing or displacing any part ofthe lubriof the Valvechamber, substantially as described.

vided with a rigid leverhandle, U, in combination with a spindle, L, provided with a hub, R, the set-screw V, turning in a lug on the hub R, and the jaw or clamp VQsaid set-screw and jaw being adapted to clamp the sleeve Q rig idly to the hub R, and the spindleLbeing conpump, all substantially as described.

3. In a pumping-lubricator, the chamber-- case A and the reciprocating plunger H,having the rigid shoulders P P, in combination with the spindle L, having rigid cam M, bearing against shoulders P P, the hub It, rigid on spindle L,provided with slipping teeth on its face, and the sleeve Q, supported on spindle L and 'provided with slipping teeth on its face bearing against the hub R, and held yieldingly thereto by spring S, and having a lever-handle whereby it is oscillated, substantiallyas described.

4. A chambered case, A, and the therein moving plunger H, provided with shoulders P P, in combination with the bracket K, adjust-able on case A, a spindle, L, and a camwheel, M, substantially as and for the purpose set forth.

In testimony whereof I afx my signature in presence of two witnesses.
